Portable elevating platform



FIG. 1 is a right, rear, top perspective view of a portable elevating platform showing my new design;

FIG. 2 is a right, rear, bottom perspective view thereof; and,

FIG. 3 is a right, front, top perspective view thereof with the platform in an elevated position.

The undisclosed left side is identical in appearance to the right side elevational view with the exception of the absence of the two switches and the two control boxes on the right and the arrangement of the pinwheel supports. 

The ornamental design for a portable elevating platform, as shown and described.
